Abstract
Lenvatinib mesylate is an oral receptor tyrosine kinase inhibitor against targets of vascular endothelial growth factor receptors 1-3, fibroblast growth factor receptors 1-4, platelet-derived growth factor receptor α, stem cell growth factor receptor, and rearranged during transfection, et al. Lenvatinib has been approved by the National Medical Products Administration of China on September 4, 2018, for the first-line treatment of patients with unresectable hepatocellular carcinoma who have not received systematic treatment before. Up to February 2023, Lenvatinib has been listed in China for more than 4 years, accumulating a series of post-marketing clinical research evidences. Based on the clinical practice before and after the launch of lenvatinib and referring to the clinical experience of other anti-angiogenesis inhibitors, domestic multidisciplinary experts and scholars adopt the Delphi method to formulate the Chinese Expert Guidance on Overall Application of Lenvatinib in Hepatocellular Carcinoma after repeated discussions and revisions, in order to provide reference for reasonable and effective clinical application of lenvatinib for clinicians.

Abstract
Objective: To understand the study method and the baseline characteristics of the survey subjects of Shandong hilly rural natural population cohort study, and provide reference for the research of the prevalence and risk factors of common chronic and non-communicable diseases. Methods: Baseline survey, including questionnaire survey, physical examination, biochemical index examination and blood and saliva collection, was conducted in local residents aged 20-79 years in Kongcun and Xiaozhi townships of Pingyin county, Shandong province, from 2017 to 2019. Shandong hilly rural natural population cohort was established and main baseline characteristics of the study subjects were statistically analyzed. Results: A total of 10 296 study subjects aged 54.45 years were included in the study, in whom 40.6% were males. Among the study subjects, 88.3% had education level of junior high school or below, 62.1% were famers, and 90.7% were married. Smokers accounted for 45.6% of men and 0.9% of women, and drinkers accounted for 65.8% of men and 3.0% of women, respectively. The self-reported rates of hypertension, diabetes, coronary heart disease, stroke and tumors were 19.8%, 3.2%, 2.8%, 2.7% and 1.2%, respectively. Conclusion: The Shandong hilly rural cohort natural population study provided important evidence for assessing the risk for common chronic and non-communicable diseases and disease prevention and control in hilly rural areas.

Abstract
Objective: To investigate the effect of placenta previa attached to cesarean scar for adverse pregnant outcomes in patients with or without placenta accreta spectrum disorders (PAS). Methods: The clinical information of patients with cesarean section history and placenta previa during the perioperative period at Peking University First Hospital from January 1st, 2015 to December 31st, 2020 were collected retrospectively. There were 53 cases without PAS and 172 cases with PAS, 153 cases with abnormally invasive placenta (containing placenta increta and placenta percreta) and 72 cases without PAS or with placenta accreta. The pregnant outcomes including rate of postpartum hemorrhage, transfusion, hysterectomy between the above groups were compared. Multivariate analysis was performed to study the factors significantly associated with PAS. Results: Pregnant women with PAS were at higher risk of adverse pregnant outcomes than those without PAS. Patients with PAS had higher incidences of hysterectomy [12.2% (21/172) vs 0(0/53); P=0.005], postpartum hemorrhage [60.5% (104/172) vs 5.7% (3/53); P<0.01] and blood transfusion [66.9% (115/172) vs 7.5% (4/53); P<0.01]. In the subgroup analysis stratified by the type of PAS, patients with abnormally invasive placenta were at higher risk of hysterectomy [13.7% (21/153) vs 0 (0/72); P<0.01], postpartum hemorrhage [66.7% (102/153) vs 6.9% (5/72); χ²=70.873, P<0.01] and blood transfusion [74.5% (114/153) vs 6.9% (5/72); χ²=90.869, P<0.01]. After multiple logistic regression, the type of creta had the positive relation with postpartum hemorrhage (OR=27.622, 95%CI:9.873~77.280; P<0.01) and blood transfusion (OR=36.912, 95%CI:13.239~102.922; P<0.01). There were no significant correlations between adverse pregnant outcomes and the type of placenta previa or the times of cesarean section (all P>0.01). Conclusions: Placenta previa attached to cesarean scar without PAS or with placenta accreta could not act as the factor of predicting adverse pregnant outcomes in clinic. Placenta previa attached to cesarean scar with placenta increta or placenta percreta could increase the risk of adverse pregnant outcomes.

Abstract
BACKGROUND Acne vulgaris is widespread across the world. Mapping the latest magnitudes and temporal trends of acne vulgaris provides the essential foundation for targeted public policies at the national, regional, and global levels. METHODS Complying with the framework of the Global Burden of Disease 2019 Study, the incidence, prevalence and disability-adjusted life years (DALYs) on acne vulgaris were retrieved in 204 countries and regions from 1990 to 2019. The average annual percentage change was calculated to depict the temporal trends in age-standardized rates (ASRs) of acne vulgaris burden by region, sex, and age. RESULTS Globally, 117.4 [95% uncertainty interval (UI): 103.0, 133.7] million incident cases of acne vulgaris, 231.2 million (95% UI: 208.2, 255.5) prevalent cases and 5.0 (95% UI: 3.0, 7.9) million DALYs were estimated in 2019, with about 47% increase compared with 1990. Moreover, the overall ASRs of acne vulgaris increased by around 0.55% annually over the past three decades. We observed huge disparities in ASRs of acne vulgaris with its changing trends in sex, location, and age. The ASR of acne vulgaris among women was around 1.3 times that of men, but the gender difference was narrowed for the pronounced increase among men. The ASRs of acne vulgaris were higher in high-income regions, but the increasing trend was more pronounced in other regions. CONCLUSION The burden rate of acne vulgaris continues to increase in almost all countries. Understanding the specific characteristics of acne vulgaris burden is essential to formulate more effective and targeted interventions for controlling acne burden.

Abstract
PURPOSE Ataxia-Telangiectasia Mutated (ATM) has been implicated in the risk of several cancers, but establishing a causal relationship is often challenging. Although ATM single-nucleotide polymorphisms have been linked to melanoma, few functional alleles have been identified. Therefore, ATM impact on melanoma predisposition is unclear. METHODS From 22 American, Australian, and European sites, we collected 2,104 familial, multiple primary (MPM), and sporadic melanoma cases who underwent ATM genotyping via panel, exome, or genome sequencing, and compared the allele frequency (AF) of selected ATM variants classified as loss-of-function (LOF) and variants of uncertain significance (VUS) between this cohort and the gnomAD non-Finnish European (NFE) data set. RESULTS LOF variants were more represented in our study cohort than in gnomAD NFE, both in all (AF = 0.005 and 0.002, OR = 2.6, 95% CI = 1.56-4.11, p < 0.01), and familial + MPM cases (AF = 0.0054 and 0.002, OR = 2.97, p < 0.01). Similarly, VUS were enriched in all (AF = 0.046 and 0.033, OR = 1.41, 95% CI = 1.6-5.09, p < 0.01) and familial + MPM cases (AF = 0.053 and 0.033, OR = 1.63, p < 0.01). In a case-control comparison of two centers that provided 1,446 controls, LOF and VUS were enriched in familial + MPM cases (p = 0.027, p = 0.018). CONCLUSION This study, describing the largest multicenter melanoma cohort investigated for ATM germline variants, supports the role of ATM as a melanoma predisposition gene, with LOF variants suggesting a moderate-risk.

Abstract
Objective: To explore the clinical manifestations, imaging features, pathological features, diagnosis and treatment of pulmonary mucosal-associated lymphoid tissue(MALT)lymphoma concurrent with lung squamous cell carcinoma, and to improve the understanding of this disease. Methods: Using "Pulmonary mucosa-associated lymphoid tissue, squamous cell carcinoma" as the search term, from January 1, 1983 to August 31, 2020, a total of 3 cases were retrieved in the PubMed database. In the Wanfang database, using "Lung mucosa-associated lymphoid tissue, lung squamous cell carcinoma" as the search term, from January 1, 1990 to August 31, 2020, a total of 1 related document was retrieved. In the CNKI database, "(lung) mucosa-associated lymphoid tissue lymphoma, (lung) squamous cell carcinoma" was used as the search term, and no relevant case reports were retrieved. Results: A 64-year-old man was admitted to the hospital because of chest tightness and shortness of breath for 10 days, cough and fever for one day. Enhanced CT of the chest showed a soft tissue mass shadow in the right lower hilar area, with obstruction of the adjacent bronchus, and local mild enhancement, suggesting of right lower lung cancer. In addition, the CT scan also showed consolidated shadows in the lower lobes of both lungs, scattered nodules, multiple lymphadenopathy in the mediastinum, and a small amount of pleural effusion on the right. Under bronchoscopy, a cauliflower-like neoplasm was seen at the opening of the lower right basal section, about 7 mm×8 mm, and biopsy showed that part of the mucosal structure was destroyed, with disappearance of the squamous epithelial layer, and the nuclei were large and deeply stained, and some were distributed in nests, with poor keratinization and a small amount of necrosis, and fibrous tissue reaction. Immunostaining revealed that the tumor was positive for p40, CK5/6 and EGFR and negative forTTF-1, NapsinA, PD-L1, p53, with about 30% Ki-67 positive cells. A puncture biopsy of the right lower lobe showed that the alveolar cavity was filled with nested lymphoid cells, consisting of small lymphocytes, central cell-like cells and monocyte-like cells, with occasionally large cells. Immunostaining revealed CD20+, CD79a+, scattered CD3+, Bcl2+, SMA vascular+, Bcl6-, CK-, CD10-, CyclinD1-, with about 3% Ki-67 positive cells. The histopathological examinations confirmed the diagnosis of mucosal-associated lymphoid tissue extranodal marginal zone lymphoma(MALT lymphoma),and lung squamous cell carcinoma. Conclusions: Pulmonary mucosa-associated lymphoid tissue lymphoma complicated with lung squamous cell carcinoma is rare and easy to be missed and misdiagnosed. Chest CT imaging shows single or multiple nodules, mass shadows or consolidation, often accompanied by air-bronchial signs in the lesion, bronchiectasis, ground glass density around the lesion, hilar and mediastinal lymphadenopathy. Occasionally, pleural effusion can be seen. Lung biopsy is the gold standard for diagnosis.

Objective: To explore the clinical value of serum des-γ-carboxy prothrombin (DCP) in predicting hepatocellular carcinoma recurrence after liver transplantation. Methods: A total of 115 cases with hepatocellular carcinoma who underwent liver transplantation in Zhongshan Hospital Affiliated to Fudan University from October 2016 to December 2018 were retrospectively analyzed. Receiver operating characteristic curve analysis, Mann-Whitney U test, Kaplan-Meier method, Log-Rank test, χ2 test, univariate and multivariate Cox regression analysis and other statistical methods were used to explore the value of DCP in predicting tumor recurrence after liver transplantation and its correlation with clinicopathological characteristics. Results: The preoperative serum DCP level in recurrent population after liver transplantation was significantly higher than that in non-recurrent population (P < 0.001). The optimal cut-off value of preoperative DCP for predicting recurrence was 200mAU/ml with the use of receiver operating characteristic curve. The sensitivity, specificity, Youden's index and the receiver operating characteristic curve was 87.90%, 57.30%, 0.452, and 0.726, respectively. Survival analysis results grouped by this cut-off value showed that patients with preoperative DCP ≥200mAU/ml had a higher probability of recurrence (P < 0.001). Further, subgroup survival analysis showed that patients with preoperative DCP≥200 mAU/ ml had a higher probability of recurrence than other cases of alpha-fetoprotein negative subgroup, cumulative tumor diameter ≤ 9 cm subgroup and Milan criteria subgroup (P < 0.05). Cox regression analysis showed that preoperative DCP≥200 mAU/ ml (P = 0.017) and cumulative tumor diameter > 9 cm (P = 0.014) was an independent risk factor for recurrence after liver transplantation. χ (2) test results showed that preoperative serum DCP level was correlated with gender, serum gamma glutamyltransferase level, serum alpha fetoprotein level, cumulative tumor diameter, vascular invasion, tumor differentiation and liver cancer transplant criteria (P < 0.05). Conclusion: Preoperative serum DCP can be used as a supplement to the existing liver cancer transplant criteria to predict hepatocellular carcinoma recurrence after liver transplantation. In addition, the accurate screening of patients with low risk of HCC recurrence after liver transplantation can improve the prognosis and efficacy of liver transplant patients.

Abstract
Objective: To study the effects of miR-16-5p on proliferation, migration and invasion of osteosarcoma cells and its mechanism. Methods: Quantitative polymerase chain reaction (qPCR) and Western blotting were used to detect the mRNA and protein expression of miR-16-5p and TSPAN15 in human normal osteoblasts hFOB 1.19 and osteosarcoma cells MG63, Saos2 and HOS. The miR-16-5p or si-TSPAN15 was transfected into MG63 cells to observe its role in cell proliferation, migration and invasion. Cell proliferation was measured with MTT assay, cell migration and invasion were examined by Transwell, and the protein expression of CyclinD1, matrix metalloproteinase 2 (MMP-2), MMP-9, tetraspanin 15 (TSPAN15), phospha-tidylinositol3-kinase(p-PI3K) and phospha-protein kinase B(p-AKT) were determined by using Western blotting. The starbase website prediction combined with dual luciferase gene reporter assay was performed to analyze the targeting relationship between miR-16-5p and TSPAN15. miR-16-5p and pcDNA-TSPAN1 were co-transfected to assess the effect of high expression of TSPAN15 on overexpression of miR-16-5p-induced proliferation, migration and invasion of MG63 cells. Data comparison between the two groups was performed by using t test. Results: Compared with hFOB 1.19 cells (1.00±0.12), the expression of miR-16-5p was significantly decreased in MG63, Saos2 and HOS cells (0.32±0.05, 0.40±0.04, 0.45±0.06, respectively)(F=156.204, P<0.05), and TSPAN15 mRNA and protein levels were greatly increased (F=71.718, 110.350, both P<0.05). Overexpression of miR-16-5p obviously reduced the expression of CyclinD1, MMP-2, MMP-9 protein, cell viability, cell migration and invasion (F=150.136,117.228, 154.971, 89.479, 98.373, 130.880, all P<0.05) in MG63 cells. Knockdown of TSPAN15 greatly reduced CyclinD1, MMP-2, MMP-9 protein levels, cell survival rate, cell migration, and invasion number (F=93.206, 107.030, 109.326, 115.625, 146.113, 139.300, all P<0.05). Overexpression of miR-16-5p markedly decreased the expression of p-PI3K and p-AKT protein in MG63 cells (F=156.755, 181.419, both P<0.05). miR-16-5p targeted to regulate the expression of TSPAN15. High expression of TSPAN15 partially reversed the inhibitory effect of miR-16-5p on TSPAN15, CyclinD1, MMP-2, MMP-9, p-PI3K, p-AKT protein expression, cell viability, cell migration number and invasion number in MG63 cells. Conclusion: miR-16-5p inhibits the proliferation, migration and invasion of osteosarcoma cells by targeting the TSPAN15 gene and regulating the PI3K/AKT signaling pathway.

Abstract
Objective: To analyze the molecular characteristics of Listeria monocytogenes strains from ready-to eat food in China. Methods: A total of 239 Listeria monocytogenes strains isolated from ready-to-eat food in 2017, all strains underwent whole-genome sequencing (WGS) , and comparisons uncovered population structure derived from lineages, clonal complex, serogroups, antimicrobial susceptibility and virulence, which were inferred in silico from the WGS data. Core genome multilocus sequence typing was used to subtype isolates. Results: All strains were categorized into three different lineages, lineage Ⅱ was the predominant types in food, and IIa was the main serogroups. CC8, CC101 and CC87 were the first three prevalent CCs among 23 detected CCs, accounting for 49.4%. Only 4.6% (11 isolates) of tested strains harbored antibiotic resistance genes, which were mostly trimethoprim genes (7 isolates, 2.9%). All strains were positive for LIPI-1, and only a part of strains harbored LIPI-3 and LIPI-4, accounting for 13.8% (33 isolates) and 14.2% (34 isolates), respectively. ST619 carried both LIPI-3 and LIPI-4. 51.5% (123 isolates) of strains carried SSI-1, and all CC121 strains harbored SSI-2. Different lineages, serogroups and CCs can be separated obviously through cgMLST analysis, and 24 sublineages were highly concordant with CCs. Conclusion: Ⅱa was the main serogroups in ready-to-eat food isolates in China; CC8, CC101 and CC87 were the prevalent CCs, and CC87 isolates was hypervirulent isolates, cgMLST method can be adopted for prospective foodborne disease surveillance and outbreaks detection.

Abstract
The blue-eggshell and dwarf traits have an important economic value in poultry production. Using a genetic aggregation-based strategy, the molecular marker-assisted selection technology was jointly used to provide a rapid breeding method for pure strain chickens simultaneously with hens exhibiting the blue-eggshell and dwarf traits. Overall, 80 male dwarf chickens and 1,000 hybrid blue-eggshell hens (F0) were used for the hybridization experiment. Subsequently, the crossing of F1 or F2 chicks was performed in succession. The F1 and F2 chicks were respectively detected by the joint molecular markers of the solute carrier organic anion transporter family, namely, 1B3 (SLCO1B3) and the growth hormone receptor (GHR) genes, which relate to blue-eggshell and dwarf traits. Meanwhile, the selection of blue-eggshell and dwarf phenotypes was used to validate the data obtained by the molecular markers. The results showed that F1 chicks included the heterozygous and wild-type of SLCO1B3, as well as the homozygous (hens) and heterozygous (roosters) of GHR. However, F2 chicks included 3 different genotypes of both SLCO1B3 and GHR. Ultimately, 196 F1 roosters (concurrently with heterozygous genotype of SLCO1B3 and GHR) and 1,073 F1 hens (concurrently with heterozygous genotype of SLCO1B3 and homozygous genotype of GHR) were obtained from the initial 10,040 F1 chicks. Further, 27 F2 roosters and 345 F2 hens, which simultaneously carried the homozygous genotype of SLCO1B3 and GHR, were screened from the initial 6,000 F2 chicks. Data obtained on the blue-eggshell and dwarf phenotypes were consistent with the results by molecular markers. Similarly, the purity verification of the strain obtained through 2 crossing experiments (F0♂ × F2♀ and F2♂ × F2♀) revealed that all chickens had the blue-eggshell and dwarf traits, supporting that the obtained F2 strain was pure. In summary, for the first time, we successfully bred a pure strain chicken with blue-eggshell and dwarf traits by jointly using the molecular markers of the SLCO1B3 and GHR genes. Our study provides a new method for the rapid cultivation of new chicken strains.

Abstract
With the continuous development of endovascular surgery, thoracic endovascular aortic repair (TEVAR) has gradually replaced traditional open surgery and has become the preferred treatment strategy for Stanford type B aortic dissection. However, the disadvantage of the short proximal landing zone greatly limited the indication of TEVAR surgery and affected the prognosis. In recent years, many strategies such as hybrid surgery, in vitro fenestrated and branched aortic endo-graft, chimney technique, in-situ fenestration technique, etc., have been developed, which greatly broadens the TEVAR indication and improved the prognosis.

Abstract
Liver cancer is one of the most common malignant tumors in China, ranking fifth in malignant tumors and the third in tumor-related deaths. As a membrane-related protein, the asymmetric distribution of cell fate determinant Numb plays a key role in cell differentiation. Research reports that Numb may be closely associated to the occurrence and development of tumors. Recently, scholars have gradually valued its important role in liver cancer. This article briefly reviews the structure of Numb molecule, relationship between Numb and tumorigenesis, the molecular mechanism of Numb-regulated tumors, and the role of Numb in the development of liver cancer.

Abstract
Abstract
TP53 is a well-known tumor suppressor gene and mutations in TP53 are the most frequent genomic event in most cancers including breast cancer. Recent studies have shown that the frequency, spectrum, timing, and clinical implications of TP53 mutations varied in different molecular subtypes of breast cancer. For example, the frequency of TP53 mutations is the highest in basal-like subtype and lowest in luminal A tumors. However, the evaluation of TP53 protein expression, as a surrogate for TP53 mutations, in large studies in the context of tumor subtypes is limited. In addition, the etiologic relevance of TP53 expression is yet to be investigated. The goal of this study is to evaluate the association of clinical and breast cancer risk factors with TP53 expression, measured using immunohistochemistry (IHC), in breast cancer molecular subtypes. The analysis included 7,226 women with invasive breast cancer who were diagnosed and treated in a tertiary hospital in Beijing, China. Subtypes were defined as Luminal A: ER+ and PR+, HER2–, and low grade (grades 1 or 2); luminal B/HER2–: ER+ and/or PR+, HER2–, and high grade (grade 3); luminal B/HER2+: ER+ and/or PR+, HER2+ (regardless of grade); HER2-enriched: ER–, PR–, and HER2+; Triple-negative (TN): ER–, PR–, and HER2–. As expected, positive TP53 staining showed the lowest frequency in the luminal A (46%) and highest in the TN (61%) and HER2-enriched (63%) subtypes (P-value <0.001). Overall and particularly in luminal A patients, positive TP53 staining was associated with higher frequencies of aggressive tumor features such as higher grade, larger tumor size, higher proliferative index, and EGFR expression. Compared with TP53– patients, TP53+ patients were more likely to have younger ages at onset and increased parity, but these associations were largely driven by the luminal A subtype [OR (95% CI) vs nulliparity = 2.67 (1.59, 4.51); 2.63 (1.52, 4.55); 3.68 (2.01, 6.72) for 1, 2, and ≥3 children, respectively (P-trend = 0.006)]. Luminal A/TP53+ patients were also more likely to have breastfed [OR (95% CI) ever vs never = 1.38 (1.03, 1.85)] than luminal A/TP53– patients. These findings suggest that TP53 IHC staining might be used to further refine the classification of luminal A breast cancer into subgroups with distinct clinical and etiologic relevance.

Abstract
Objective: To investigate the effects of continuous positive airway pressure (CPAP) on periodic limb movements during sleep (PLMS) in patients with obstructive sleep apnea (OSA). Methods: The polysomnography (PSG) data of 828 consecutive OSA outpatients from January 2015 to January 2017 who had undergone overnight CPAP titration were analyzed retrospectively. On the basis of changes in periodic limb movements index (PLMI) values (cut off level≥15/h) from baseline PSG (BPSG) to CPAP titration PSG, patients were assigned to one of the following four groups: persistent, CPAP-emergent, CPAP-disappeared, and non-PLMS. Results: Among 828 patients, 756 (91.3%) were male and 72 (8.7%) were female. The mean age was (45.7±10.7) years old, the mean body mass index (BMI) was (27.6±3.5) kg/m(2). The rate of patients was 3.9% in the persistent group, 10.3% in the CPAP-emergent group, 7.5% in the CPAP-disappearance group, and 78.4% in the non-PLMS group. Multivariate Logistic regression analysis revealed that female appeared to be associated with the persistent group (P=0.004); older age and higher apnea-hypopnea index (AHI) on BPSG appeared to be associated with the CPAP-emergent group (P=0.012, 0.030). On the other hand, older age was negatively associated with the non-PLMS group (P=0.006). Conclusion: Elderly patients with higher AHI at BPSG may present with CPAP-emergent PLMS.

Abstract
Abstract
Epidemiological studies have shown that associations between breast cancer risk and risk factors vary by tumor pathology such as estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) status. Mammographic density (MD) is a strong risk factor for breast cancer, but data on the association between MD and breast cancer subtypes have been inconsistent and most studies have been conducted among Western women. The goal of this study was to evaluate the association between MD and breast cancer subtypes in an Asian population where the proportion of dense breast tissue is higher but the overall breast cancer incidence rate is much lower compared with Western countries. Breast cancer cases from a cancer hospital in Beijing, China with MD and ER, PR, and HER2 immunohistochemical (IHC) data were included in this analysis. To reduce subtype misclassification, we excluded cases that were HER2 2+ for IHC but had no FISH data. Tumor subtypes were defined as Luminal A (ER+ or PR+ and HER2-, N=376), Luminal B (ER+ or PR+ and HER2+, N=97), HER2-overexpressing (ER- and PR- and HER2+, N=71), and triple negative (TN, ER- and PR- and HER2-, N=66). MD was assessed on digital mammograms and categorized into four levels using the Breast Imaging Reporting and Data System (BI-RADS) scoring system (a=almost entirely fat, b=scattered fibroglandular densities, c=heterogeneously dense, and d=extremely dense). Because there were few cases with almost entirely fat breasts, we combined MD levels "a" and "b" as our reference group. Polychotomous logistic regression was used to assess the association between MD and breast cancer subtypes with the adjustment of age, menopausal status, parity, age at menarche, and body mass index (BMI) since all these variables showed significant inverse associations with MD (P=0.002 for age at menarche and P<0.0001 for all others). Compared with luminal A cases, cases with HER2-overexpressing tumors were significantly more likely to have extremely dense breasts (Odds ratio [OR], 2.6; 95% confidence interval [CI], 1.2-5.7). Cases with luminal B (OR, 2.1, 95% CI, 1.2-3.9) and TN (OR, 2.9, 95% CI, 1.5-5.8) tumors had significantly higher proportions of heterogeneously dense but not extremely dense tissue compared with luminal A cases. Our data suggest that higher MD is associated with more aggressive tumor subtypes, particularly the HER2-overexpressing subtype among Chinese breast cancer cases. If confirmed in larger studies, these results may provide insight into the higher incidence rates of HER2-overexpressing breast cancer seen among young Asian American and Asian women.

Abstract
This study aimed to conduct a systematic review to sum up evidence of the associations between different aspects of night shift work and female breast cancer using a dose-response meta-analysis approach. We systematicly searched all cohort and case-control studies published in English on MEDLINE, Embase, PSYCInfo, APC Journal Club and Global Health, from January 1971 to May 2013. We extracted effect measures (relative risk, RR; odd ratio, OR; or hazard ratio, HR) from individual studies to generate pooled results using meta-analysis approaches. A log-linear dose-response regression model was used to evaluate the relationship between various indicators of exposure to night shift work and breast cancer risk. Downs and Black scale was applied to assess the methodological quality of included studies. Ten studies were included in the meta-analysis. A pooled adjusted relative risk for the association between 'ever exposed to night shift work' and breast cancer was 1.19 [95% confidence interval (CI) 1.05-1.35]. Further meta-analyses on dose-response relationship showed that every 5-year increase of exposure to night shift work would correspondingly enhance the risk of breast cancer of the female by 3% (pooled RR = 1.03, 95% CI 1.01-1.05; Pheterogeneity < 0.001). Our meta-analysis also suggested that an increase in 500-night shifts would result in a 13% (RR = 1.13, 95% CI 1.07-1.21; Pheterogeneity = 0.06) increase in breast cancer risk. This systematic review updated the evidence that a positive dose-response relationship is likely to present for breast cancer with increasing years of employment and cumulative shifts involved in the work.

Abstract
Abstract
Background: E-cadherin is a tumor suppressor gene involved in cell-cell adhesion, epithelial-to-mesenchymal transitions (EMT) and invasion. Loss of E-cadherin expression is strongly associated with lobular breast cancers, which exhibit single cell patterns of infiltration and are often estrogen receptor positive. We sought to determine if relative risk estimates for 19 established breast cancer susceptibility loci were modified by E-cadherin breast tumor tissue expression.
Methods: Case-control analyses included up to 1885 invasive breast cancer cases and 2366 age and site matched controls aged 20–74 years from the Polish Breast Cancer Study (PBCS), a population based case-control study conducted in Poland from 2000–2003. Genotyping of the 19 single nucleotide polymorphisms (SNPs) was performed using TaqMan® assays. Tissue expression of E-cadherin was assessed using immunohistochemical (IHC) staining of tissue microarrays and IHC results were scored as the product of percent positive tumor cells × intensity. Tumors having a score of <10 were classified as E-cadherin low and those with a score ≥10 as E-cadherin high. Polytomous logistic regression models adjusted for age and study site were used to estimate odds ratios (OR) and 95% confidence intervals (95% CI) for each breast cancer subtype, defined by E-cadherin expression levels, compared to controls. Case-only data from the PBCS (N = 797) and the Study of Epidemiology and Risk Factors in Cancer Heredity, SEARCH (N = 2155) was used in logistic regression models to test for heterogeneity of SNPs by E-cadherin expression.
Results: Three SNPs suggested significant heterogeneity by E-cadherin expression in the PBCS: rs2046210 at 6q25.1(ESR1) [per-allele ORs (95% CI); 1.53 (1.19–1.98) for E-cadherin low tumors and 0.99 (0.86–1.14) for E-cadherin high tumors, P-heterogeneity = 0.002]; rs1045485 at 10p14 (CASP8) [per-allele ORs (95% CI); 0.62 (0.41–0.93) for E-cadherin low tumors and 0.98 (0.81–1.18) for E-cadherin high tumors, P-heterogeneity = 0.04]; and rs11249433 at 1p11.2 (NOTCH2/FCGR1B) [per-allele ORs (95% CI); 1.29 (1.02–1.64) for E-cadherin low tumors and 1.01 (0.88–1.15) for E-cadherin high tumors, P-heterogeneity = 0.06]. Combined case-only analysis of PBCS and SEARCH for these three SNPs showed significant heterogeneity by E-cadherin expression for rs11249433 [Interaction OR (95% CI); 1.19 (1.05–1.36), P-heterogeneity = 0.007] and rs1045485 [Interaction OR (95% CI); 0.69 (0.53–0.90), P-heterogeneity = 0.007]. The association with rs2046210 [Interaction OR (95% CI); 1.12 (0.61–2.03), P-heterogeneity = 0.73] did not remain significant in combined analyses.
Conclusion: Our findings provide evidence that associations for breast cancer susceptibility loci vary by E-cadherin tumor tissue expression, which has not been described previously. Specifically, our results suggest that the genetic markers rs11249433 and rs1045485 may preferentially modify risk for tumors with low or absent E-cadherin expression in two independent data sets.

Abstract
Background Carrying the cyclin-dependent kinase inhibitor 2A (CDKN2A) germline mutations is associated with a high risk for melanoma. Penetrance of CDKN2A mutations is modified by pigmentation characteristics, nevus phenotypes, and some variants of the melanocortin-1 receptor gene (MC1R), which is known to have a role in the pigmentation process. However, investigation of the associations of both MC1R variants and host phenotypes with melanoma risk has been limited. Methods We included 815 CDKN2A mutation carriers (473 affected, and 342 unaffected, with melanoma) from 186 families from 15 centers in Europe, North America, and Australia who participated in the Melanoma Genetics Consortium. In this family-based study, we assessed the associations of the four most frequent MC1R variants (V60L, V92M, R151C, and R160W) and the number of variants (1, ≥2 variants), alone or jointly with the host phenotypes (hair color, propensity to sunburn, and number of nevi), with melanoma risk in CDKN2A mutation carriers. These associations were estimated and tested using generalized estimating equations. All statistical tests were two-sided. Results Carrying any one of the four most frequent MC1R variants (V60L, V92M, R151C, R160W) in CDKN2A mutation carriers was associated with a statistically significantly increased risk for melanoma across all continents (1.24 × 10−6 ≤ P ≤ .0007). A consistent pattern of increase in melanoma risk was also associated with increase in number of MC1R variants. The risk of melanoma associated with at least two MC1R variants was 2.6-fold higher than the risk associated with only one variant (odds ratio = 5.83 [95% confidence interval = 3.60 to 9.46] vs 2.25 [95% confidence interval = 1.44 to 3.52]; Ptrend = 1.86 × 10−8). The joint analysis of MC1R variants and host phenotypes showed statistically significant associations of melanoma risk, together with MC1R variants (.0001 ≤ P ≤ .04), hair color (.006 ≤ P ≤ .06), and number of nevi (6.9 × 10−6 ≤ P ≤ .02). Conclusion Results show that MC1R variants, hair color, and number of nevi were jointly associated with melanoma risk in CDKN2A mutation carriers. This joint association may have important consequences for risk assessments in familial settings.

Abstract
Background: Previous prospective studies have found an association between prolactin (PRL) levels and increased risk of breast cancer. Using data from a population-based breast cancer case–control study conducted in two cities in Poland (2000–2003), we examined the association of PRL levels with breast cancer risk factors among controls and with tumour characteristics among the cases. Methods: We analysed PRL serum levels among 773 controls without breast cancer matched on age and residence to 776 invasive breast cancer cases with available pretreatment serum. Tumours were centrally reviewed and prepared as tissue microarrays for immunohistochemical analysis. Breast cancer risk factors, assessed by interview, were related to serum PRL levels among controls using analysis of variance. Mean serum PRL levels by tumour characteristics are reported. These associations also were evaluated using polytomous logistic regression. Results: Prolactin levels were associated with nulliparity in premenopausal (P=0.05) but not in postmenopausal women. Associations in postmenopausal women included an inverse association with increasing body mass index (P=0.0008) and direct association with use of recent/current hormone therapy (P=0.0006). In case-only analyses, higher PRL levels were more strongly associated with lobular compared with ductal carcinoma among postmenopausal women (P=0.02). Levels were not different by tumour size, grade, node involvement or oestrogen receptor, progesterone receptor, or human epidermal growth factor receptor 2 status. Conclusions: Our analysis demonstrates that PRL levels are higher among premenopausal nulliparous as compared with parous women. Among postmenopausal women, levels were higher among hormone users and lower among obese women. These results may have value in understanding the mechanisms underlying several breast cancer risk factor associations.

Abstract
BACKGROUND The naevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant multisystem disorder with variable expression. NBCCS patients have variable susceptibility to development of basal cell carcinoma (BCC). Previous studies have shown that polymorphisms of some metabolic genes encoding the cytochrome p450 (CYP) and glutathione-S-transferase (GST) enzymes influenced the numbers of BCCs in sporadic BCC cases. OBJECTIVE To determine whether allelic variants of these genes contribute to the variation in numbers of BCCs observed in NBCCS families. METHODS Genotyping and analysis was carried out in 152 members (69 affected and 83 unaffected) of 13 families with NBCCS for seven polymorphisms in five metabolic genes including CYP1A1, CYP2D6, GSTM1, GSTP1, and GSTT1. RESULTS GSTP1 Val105 and GSTP1 Val114 alleles were significantly associated with fewer BCC numbers (odds ratio (OR)105 = 0.55 (95% confidence interval, 0.35 to 0.88); OR114 = 0.20 (0.05 to 0.88)). The Val(105) allele showed a dose dependent effect (OR(Ile/Val) = 0.58 (0.34 to 0.88); OR(Val/Val) = 0.34 (0.14 to 0.78)). In addition, fewer jaw cysts were observed in carriers of the three p450 polymorphisms (CYP1A1m1, CYP1A1m2, and CYP2D6*4) (OR(CYP1A1m1) = 0.27 (0.12 to 0.58); OR(CYP1A1m2) = 0.25 (0.08 to 0.78); OR(CYP2D6*4) = 0.33 (0.18 to 0.60)). CONCLUSIONS Genetic variants might contribute to the variation in numbers of BCCs and jaw cysts observed in NBCCS families.

Abstract
OBJECTIVE To determine the preventive and regressive effects of total flavones of metasequosia (TFM) on left ventricular hypertrophy in rats. METHOD Left ventricular hypertrophy was inducedin by partial ligation of abdominal aorta. The rats were given ig TFM(4, 40, 400 mg.kg-1.d-1) for six weeks. RESULT TFM markedly reduced the HW/BW, LVW/BW, myofibril diameter and Ca2+ content in left ventricles but the systolic blood pressure (SBP) in rats wasn't obviously influenced. CONCLUSION TFM can prevent and reverse the left ventricular hypertrophy due to pressure overload in rats. The mechanism may be related to its calcium antagonistic properties.

Abstract
A novel flow-injection (FIA) system, for the rapid and direct determination of both total ammonia (T[NH3]) and total carbon dioxide (T[CO2]) in clinical blood samples, has been developed. Samples were injected into a carrier stream of H2O, then emerged with a reagent stream, where the analyte was converted into a gaseous species and diffused across a PTFE gas-permeable membrane into an acceptor stream. The trapped NH3/CO2 in the acceptor was determined on line by a bulk acoustic wave (BAW) impedance sensor. At a through-put of 20 and 65 h(-1), the proposed system exhibited a linear frequency response up to 200 micromol l(-1) ammonium and 20 mmol l(-1) bicarbonate with a detection limit of 1.0 and 10 micromol l(-1), respectively. Results obtained for T(NH3) in serum and T(CO2) in plasma were in agreement with those obtained by the conventional glutamate dehydrogenase (GDH) method and gas-sensing electrode method, respectively. The effects of composition of acceptor stream, cell constant of conductivity electrode, sample volume, flow rate and potential interferents on the FIA signals were also discussed.

Abstract
Paired helical filaments (PHF) characteristic of Alzheimer neurofibrillary lesions are known to contain a modified form of microtubule associated protein tau. These proteins, PHF-tau, differ from normal tau in the extent and the site of phosphorylation. To determine whether PHF-tau, tau proteins from normal adult brains (N-tau), tau proteins from Alzheimer brains not associated with PHF (A-tau), and tau proteins from fetal brains (F-tau) differ in racemization, these proteins were compared for their D-aspartate content. The results demonstrated that PHF-tau contain more D-aspartate than N-tau, A-tau and F-tau. The average percentage D-aspartate for these proteins, after a correction for background, are 4.9%, 2.8%, 1.6%, and 1% for PHF-tau, N-tau, A-tau and F-tau, respectively. It remains to be determined if the increase in D-aspartate is a consequence of PHF formation. It is also unknown if the change in D-aspartate content in PHF-tau is associated with phosphorylation, which alters the susceptibility of tau to proteolysis.

Abstract
Increasing the plasma phenylalanine concentration to levels as high as 0.560-0.870 mM (over ten times normal levels) had no detectable effect on the rate of brain protein synthesis in adult rats. The average rates for 7-week-old rats were: valine, 0.58 +/- 0.05%/h, phenylalanine, 0.59 +/- 0.06%/h, and tyrosine, 0.60 +/- 0.09%/h, or 0.59 +/- 0.06%/h overall. Synthesis rates calculated on the basis of the specific activity of the tRNA-bound amino acid were slightly lower (4% lower for phenylalanine) than those based on the brain free amino acid pool. Similarly, the specific activities of valine and phenylalanine in microdialysis fluid from striatum were practically the same as those in the brain free amino acid pool. Thus the specific activities of the valine and phenylalanine brain free pools are good measures of the precursor specific activity for protein synthesis. In any event, synthesis rates, whether based on the specific activities of the amino acids in the brain free pool or those bound to tRNA, were unaffected by elevated levels of plasma phenylalanine. Brain protein synthesis rates measured after the administration of quite large doses of phenylalanine (> 1.5 mumol/g) or valine (15 mumol/g) were in agreement (0.62 +/- 0.01 and 0.65 +/- 0.01%/h respectively) with the rates determined with infusions of trace amounts of amino acids. Thus the technique of stabilizing precursor-specific activity, and pushing values in the brain close to those of the plasma, by the administration of large quantities of precursor, appears to be valid.

Abstract
In skeletal muscle the activation of phosphorylase b is catalyzed by phosphorylase kinase. Both enzymes occur in vivo as part of a multienzyme complex. The two enzymes have been imaged by atomic force microscopy and the results compared to those previously found by scanning tunneling microscopy. Scanning tunneling microscopy and atomic force microscopy have been used to view complexes between the activating enzyme phosphorylase kinase and its substrate phosphorylase b. Changes in the size and shape of phosphorylase kinase were observed when it bound phosphorylase b.

Abstract
Effects of peruvoside and neriifolin, main components of neriperside, a tevetoside extracted from Thevitia neriifolia Juss, on Na+, K(+)-ATPase activities and on [3H] ouabain binding to the Na+, K(+)-ATPase isolated from hearts of guinea pigs, dogs and cats and kidneys of guinea pigs and cats were compared with digoxin and ouabain. It was found that peruvoside and neriifolin inhibited Na+, K(+)-ATPase activities and they showed a strong competitive inhibition on [3H] ouabain binding to the enzymes isolated from various tissues. A marked species difference existed as great as that of digitalis. The mechanism of action of these 2 drugs may be similar to that of digitalis. Their inhibitory effects on the enzyme activity were stronger than their positive inotropic effects, while both actions of digitalis were parallel quantitatively. There may be some differences in the modulation of the intracellular Ca2+ between neripersides and digitalis.

Abstract
Two new microscopic techniques make it possible to obtain images of biologically interesting molecules directly in air, vacuum, or under water. Scanning tunneling microscopy and atomic force microscopy both have the capacity to visualize atoms on the surface of rigid structures and provide details of molecular structure for lipids, proteins, carbohydrates, and nucleic acids. In addition to providing visualizations of individual molecules, these scanning probe techniques allow direct imaging of complexes between molecules or between molecules and higher-order subcellular structures such as membranes and cytoskeletal components. Both microscopes can be operated under a variety of ambient conditions ranging from high vacuum to above atmospheric pressure. Specimens need not be dry; both techniques have been used to image molecules in aqueous media under nearly physiological conditions. It is proposed that as these techniques mature they will allow direct observation of many molecular interactions under physiological conditions or even in vivo while they are occurring within the cell.

Abstract
Scanning tunneling microscopy (STM) has been used to examine glycogen molecules. Individual molecules were approximately ellipsoidal with dimensions in the 20- to 60-nm range. Images of the glycogen molecular surfaces have a laminar appearance. The layered features seen on the surfaces of the molecules suggest that glycogen may grow from one edge as a laminar structure to form an ellipsoid rather than originating at a central point with radial growth of the oligosaccharide chains to form a sphere. The results of these studies indicate that STM can be used to determine details of polysaccharide structures.

Abstract
Scanning tunneling microscopy (STM) has been used to examine the structures of the skeletal muscle enzymes phosphorylase and phosphorylase kinase. The interaction of these two proteins represents the last step in the process of signal transduction which results in muscle glycogen being converted into metabolic energy for use in muscle contraction. Phosphorylase b has a molecular weight of 97,000 and the dimer is seen by STM to have dimensions of 11 X 5.7 nm. Phosphorylase b has a tendency to form linear arrays of dimers on the graphite surface used as the support for STM imaging. Phosphorylase kinase is imaged as a butterfly-like object with lateral dimensions of 36 X 27 nm. The molecular thicknesses given by scanning tunneling microscopy for these two non-conducting molecules is significantly less than expected. The height measurement in STM is dependent not only on the surface topology of the object being imaged, but also on the electronic work function of the object compared to that of the graphite surface on which it lies. In addition to the individual proteins, a complex between phosphorylase and phosphorylase kinase has been observed by scanning tunneling microscopy.
